IU KOWA commences operations on: 1998,067
|Host:||National Center for Science and Technology Research|
|Telemetry Status at the NEIC:||Last Data In Less Than 10 Minutes|
Site Description: Located in the Niger River delta region of the Sahara desert in Mali continent of Africa. KOWA operates as a remote IRIS2 station with the data processor operating at the airport in Sevare and the acquisition unit operating at the Dogon village of Kowa approximately 10k from Sevare. The site uses radio modems for data transmission and solar power. A dialup modem is operational. Internet access is not available at this time. National language is French with 75% of the poulation speaking Bambara.
Vault Condition: 40 meter horizontal tunnel with approx. 10-15 meters of overburden. (solid rock), *Dry and very hot
Site Geology: Sandstone

Availability, Last 30 Days
Current IssuesReplacement STS-2 has either failed or the local operator had issues with the install. The TR240 has been moved to the primary channels (00 location code) until the problem can be resolved.
2012-08-12Since Aug. 12 (2012) timing quality has been bad. A replacement GPS antenna was installed 12 Sept 2014.
2011-11-05Power system repaired and data flow has resumed.
2011-06-11Data flow stopped due to power system failure.
2011-05-25Upgraded to Q330 digitizer.
